IRONING Application led September To all whom t may 0071 oem:

Be it known that. I, IVENDELL S. MERICK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Ironing Machines, ofwhich the following is a specification.

This invention relates to ironing machines.

It will be explained as applied to an ironing machinehaving amotordriven rotatable pressing cylinder and a hea-ted, nonrotatablepressing shoe. The' cylinder and shoe are relatively movable toward andfrom each other in assuming pressing and non-pressing positions.

With the' ordinary ironing machine the shoe will not burn the padding onthe cylinder as long as the cylinder is in motion. However, if for anycause, the cylinder stops while the heated shoe is in Contact therewith,the padding is very apt to burn, resulting in its destruction and thecreation' ot a dangerous tire hazard.

-One of the objects oi this invention is to provide an improved ironingmachine. i

Another object is to provide an ironing machine wherein the shoe andcylinder are automatically separated whenever the cylinder ceases toturn or appreciably decreases its rate of rotation.

Another object is to provide an ironing machine wherein the shoe andcylinder, when brought together to pressing position, are automaticallyheld in such condition until the rate of rotation oi. the pressingcylinder decreases.

Other objects atter appear.

Fig. 9 is an enlarged view showing the relation ot the trip and latch inlocking position.

The ironing machine has a rotatable pressing cylinder land a curvedpressing shoe 2.

, The shoe is rigidly connected at opposite ends to end frames 3 and4,.respectively. The end frames may be made of suitable material such aspressed steel or cast iron. The shoe may be heated by any suitablemeans.

Cylinder l is carried on a shaft 5 which is journaled, at opposite ends,in brackets 6 and 7. Brackets 6 and 'T are journaled on and supported bya shaft 8 which extends between and is iournaled to end frames 3 and et.The. cylinder is rotated by a motor 9 through a vertical shaft 10 andworm and gear trains11 and 12. The worm and gear trains and shaft 11 arehoused in bracket 6. Motor 9 is carried by a pair of brackets 13 and 14rigidly bolted to shaft 8 so as to be moved therewith. The motor isjournaled to brackets 13 and 14 so that it is rotatably mounted as awhole for a purpose to be hereinafter explained.

Thus when shaft 8 is rocked, as will be hereinafter described cylinder lis moved into and out of pressing position relative to shoe 2 and themotor is also rocked so that the driving gear trains remain in properengagement.

Shaft 8 has an arm 16 secured thereto at each end. Each arm 16 has asocket 17 pivotally attached to its outer end. Each socket 17 has a rod18 sliilably passing therethrough. Rods 18' are `threaded at their lowerends and slidably pass through sockets 19. Sockets 19 are respectivelypivotally carried on one arm of a. pair ot bell crank levers 20. A. pin21, passing through each rod 18, and cooperating with the correspondingsocket 17, anchors one end of the rods. The threaded end of each rod hasan adjusting nut 22 thereon which cooperates with the correspondingsocket 19 to regulate the eective length of the respective rod.

Bell crank levers 20 are rigidly secured to a shaft 25 which isjournaled in end frames 3 and 4 and have a foot rail 26 pivotallyconnected thereto. Thus t-he depression of rail 26 oscillates bell cranklevers 20 and,

. teeth of the ratchet on lever from .the shoe.

The cylinder 1s held in pressing position when it has been movedthereto.

An arm 27 is rigidlyT secured to shaft 25 so as to move therewith. Arm27 is pivotally connected to a lbell crank lever 28. One

arm of lever 28 is pivotally connected to` the front of. rail 26 by alink 29. The other arm of lever 26 is provided with-ratchet teeth 30.Ratchet teeth 30 cooperate with a latch 3l secured to journaled in endframes Band 4. Latch 3l is a substantially L shaped arm jour-naled inadisc 33 carriedon shaft 32.

Latch 3l is connected to a link SiJwhich is connected to one arm ot ahell crank lever on a shaft 36. Shaft 36 is journaled in end frames 3and 4. The other arm ol lever is connected to the frame ot motor E) l-.a link 37.

The operation -ot the machine is as tollows:

Depression of rail 26 moves the cylinder into pressing positionpreviously explained. The "rotation vot motor 9 causes the same to moveas a whole in the journals of brackets 13 and 14.' This slight movementor torque of the inotor pulls link 37 and rocks bell crank lever 35. Therocking of bell crank lever 35 moves latch 31 so .thatl it is in aposition to engage and hold one of the ratchet teeth ot lever 28 (seeThus when the rail is depressed while the motor is rotating;r thecylinder the 28 are engaged and held hy latch f-ll. While vthe motor isrunning the cylinder ma)v he released and titi' moved from pressing'position hv theoperator slightly tilting' rail 26. This tilting of therail rocks lever 2Q and its'teeth are disengaged from latch -l'l.-

As long' as the motor is running` with sufiicient speed to create apulling' i'orce or torque sufficient to rock and hold latch 3l inlocking position the cylinder is held in pressing positionluntilreleased by the operator. i l A However. should the speed ot the motordecrease, because ot interruption ot the circuit .thereto or troniothercauses, to a point where its tendency to rotate or its torque will'notcreate suiticient. pull to..hold latch 3l in lockingr position the latchrocks hac-k' to the position shown in Fig. 8; lever'28 I' shoe, a.rotatable pressing cylinder,
